DESCRIPTION:In the Iwasawa theory of p-adic Galois representations over\nt
 he cyclotomic tower\, a key role is played by Perrin-Riou's regulator\nor 
 dual exponential map (particularly for non-ordinary Galois\nrepresentation
 s). I will describe a generalisation of this map to\nIwasawa theory for ce
 rtain towers of extensions whose Galois groups\nare abelian p-adic Lie gro
 ups of dimension 2\, and some applications of\nthis construction to Galois
  representations arising from modular\nforms. This is a joint project with
  Sarah Zerbes.
